CATTLE GUARD.

Application filed April 3,

To all whom t may concern.'

Be it known that I, NICHOLAS NUMAJLYK, a citizen of Ukrainia, residingat Viiinipeg, in the Province of Manitoba and Dominion of Canada, haveinvented certain new and useful Improvements in Cattle Guards, of whichthe following is a specification.

This invention relates to new and useful improvements in cattle guards.

An important object of the invention is to provide a guard that may beplaced between adjacent poles of a fence adjoining railroad tracks or ahighway, should the wire or the like between said posts be broken down,for preventing the passage of cattle through said opening in the fence.

A further object of the invention is to provide a device of the abovementioned type which is automatic in its operation.

Other objects and advantages of the invention will be apparent duringthe course of the following description.

In the accompanying drawing forming a part of this specification and inwhich like numerals are employed to designate like parts throughout thesame,

Figure 1 is a longitudinal sectional view of the cattle guard embodyingthis invention and shows'the same in its inoperative position` Figure 2is a similar view to Fig. 1 with the exception that the guard is in itsoperative position,

Figure 3 is a top plan view, partly broken away, of the guardillustrated in Figs. 1 and 2,

Figure 4 is a detail enlarged view for showing the specific connectionbetween the platform embodied in this invention and the supporttherefor,

Figure 5 is a rear elevational view of the guard with the variouselements shown in full lines in inoperative position and in dotted linesin their operative positions,

Figure 6 is a rear elevational view of the guard with the variouselements shown in full lines in their operative positions, and

Figure 7 is a top plan View of sections of railroad track and sectionsof fencing associated therewith with the cattle guard embodying thisinvention arranged to illustrate the utility for the same.

In the drawings, wherein for the purpose of illustration is shown apreferred embodiment of this invention, the numeral 5 designates thebase or frame portion of the de- 1924. Serial No. 703,941.

vice embodying this invention and this base or frame portion consists ofthe longitudinally extending side bars 6 and the transversely extendingend bars 7.

Rotatably journaled in the opposite, longitudinally extending side bars6 are the transversely extending shafts 8. Eccentrically keyed to theseshafts 8 are the solid, cylindrically-shaped members 9` having formedtherewith the upwardly extending arms 10 which are arranged in spacedrelation to each other and are also spaced inwardly from the oppositeends of the solid cylindrically-shaped members 9. These separatelyextending arms 10 are provided with bifurcated ends 11 to which arepivotally secured the brackets 12 which are carried by the under face ofthe platform 13, as best illustrated in Figs. 1, 2 and 4.

In Figs. 1 to 3 inclusive, one of the cylindrically-shaped eccentricallymounted inembers 9 is illustrated as being provided with a lattice workgate structure 14 which extends laterally outwardly therefrom. Securedto the opposite side rails of this gate structure 14 or preferablyformed integrally therewith, are the inverted L-shaped arms 15 whichextend generally upwardly therefrom and are pivotally connected at theirouter ends to the side bars 16. These side bars 16 are provided withT-shaped outer ends, as best illustrated in Fig. 3, and are designatedby the numeral 17. Mounted upon the top faces of the longitudinallyextending side bars 6 of the base frame 5 are the longitudinally slottedguides 18 which are best illustrated in Figs. 1 and 3. In Figs. 1 to 3inclusive there is illustrated a transversely extending brace rod orstop 19 which is connected at its opposite ends to the longitudinallyextending side bars 6 of the base frame 5 and it will be seen byiuspecting Fig. 1 that the gate 14 will rest upon this stop or crossbrace 19 when the platform 13 and gate structure 14 are in theirinoperative positions.

The operation of this cattle guard will be clearly understood by adescription of the device as illustrated in Figs. 1 and 2. It isintended that the gate structure 14 possess a greater weight than theplatform 123 and for this reason the gate 14 will overbalance theplatform 13 and the various elements will normally assume the positionsas illustrated in Fig. 1. That is, the gate structure 14 will rest uponthe stop or cross brace 19 and the platform 13 will be retained in itselevated position. If weight'v is applied to the platform 13 for causingthe same to overbalance 'the gate structure 14:, the platform 13 will belowered, due to the eccentric mounting of ythe soli-dcylindrically-shaped members 9, and the gate structure 14 will beelevated into an upwardly extendingposition. It will be noted that theside bars 161have also beenbperated by themovement of the gate structure14 andl that the T- shapedheads-or ends1'74 havefbeen longitudinallymoved through the slots of`- the guide elements 18. These sider bars 16areintended tofpartially close or form barriers for the sides' of theplatform and4 when combined with the gate structure4 13 willsubstantially closeoff `three sides of the platformvl-B.

It has been previously stated that' Fig'. 7 illustratesthe utility ofthe device; In this figurethere areY illustrated theA parallel tracks 2Owhich, of course, maybe the road'- bed of a highway or other publicthoroughfare. Adjoining` the tracksZO are thefence structures 21 whichare intended toindicate fencing, around5 pastures ortfhe like wherein:Vcattle or other live stock graze; It is to be understood that thesefences: usually consist of uprights or posts 'betweerr which strands ofwire or the like arie" stretched. Bt often happens that'` the wiresbetween adjacent posts will become broken down and will leave an openingthrough' which cattle pass.'` The ideaA embodied in this invention' isVto position one of the cattle gnards illustrated; in Figs.l 1 to 6inclusiv-e between adjacent posts, such as indicated by the numerall Ain Fig.4 7, for closing. the opening previously bridged*l by the wirestrands that have been` broken. Ift will be seen by inspecting` Fig.that the frame 5 will extend at right angles' to the fence-21'y and thatthe gate structure 14EV willl be positioned in substantially ahorizontal plane or, in other words, will not ll the gap between thefence post. If, upon seeing the opening in the fence, an animalendeavors to pass through the same, it will be compelled to place itsweight upon the platform 13. This weight will cause the platform to dropwhich will elevate the gate structure 14; and move the sideba-rs 16 intothe positions illustrated in Fig. 2. The opening through the fence willthereby bevclosed and the animal will:v not'. be permitted topasstheietlirough.y After. the anima/lis weight has. been removedlfrom theplatform 13, the overbalancing weighty of the gate structure 11i willcause the platformi to bei elevated into the position illust-rated inFig;v` l and the gate structurell' willi return to a position: resting.upon the stop or-` cross brace 19.

It isitoV be understood that the for-m of this invention herewith shownand described is to betakenI as a preferred, example ofi the same,andithat variousohanges in the shape, size, and arrangement of parts maybe resorted to without departing from. the spirit of the invention orthe'` scope ofV thesub- `ioinedclaim.

Having thus described.` the invention, l claim y y In a device ofi thetype desoribedf, al base, a vertically movable platformV carried? bysaid base, a swinging gate carried by said base, side bars pivotallyconnected to: said gate and sli dably connected to said base, and meansfor causing downward movement of said platform to raiseD said gate for"bridging" one`- end: of 'said platform and for operating said side barsfor substantially bridgingl the oppositesidesoi? saidi platform.'
